Details

The XRotor M5208 Light motor uses a 58 mm frame with 4M3 mounting patterns to help match common multirotor arms and mounts.

The XRotor M5208 Light motor features an open-spoke bell design with braided three-wire leads and a clear 380KV marking for easy matching in builds.

Hobbywing XRotor M5208 Light motor is listed at 154 g with up to 5.3 kg maximum thrust and a recommended quad take-off weight of 6.5 kg.

The XRotor M5208 Light motor is positioned for varied drone use with high-temperature resistance, waterproof design, and long-endurance performance.

The XRotor M5208 Light motor features an open-face design with exposed copper windings and three pre-attached leads for straightforward wiring.

The XRotor M5208 Light motor uses a knurled shaft and circlip, pressure ring, and screw interlocking structure to help prevent loosening.

The M5208 Light setup guide recommends a 6S LiPo with XRotor Pro H60A 6S ESC and 19×5.7, 18×6.1, or 17×5.8 propellers for 1.41.9 kg thrust per rotor.
